BRAIDIN G-lViACHINE.

To all whom it may concern:

Be it known that I, EUGENE RANKIN, a subject of the King of GreatBritain and Ireland, whose post-office address and residence is 17Portman avenue, East Sheen, London, En 'land, have invented certain newand useful Tmprovements in Braiding-Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention for improvements in braiding machines relates to machinesin which an inner and outer set of bobbins are rotated in oppositedirections and in which the threads from the outer set of bobbins arepassed under and over the threads of the inner bobbins and has for itsobject to simplify the construction of such a machine by supporting boththe inner and outer sets of bobbin carriers on an axially mounted spideror table and to effect the passage of the threads by a cam motion sothat the pattern can readily be varied by means of interchangeable cams.

In the accompanying sheets of illustrative drawings, Figure l is a partsection of a machine constructed according to this invention, Fig. 2 isa part front elevation, Fig. 3 is a part plan, Fig. 4 is a diagrammaticview showing the loci of the thread passing arm. Figs. 5, 6, 7 and 8 aredetail views showing the respective positions of the thread passing armin relation to the carrier disk when passing the thread.

In carrying out this invention the two spiders a Z) are mountedcoaxially on a central hearing or tube support 0 and are driven inopposite directions by means of the bevel gear wheels or Z) respectivelywhich in turn receive their motion from the driving shaft e and bevelpinion (Z. The spider a is rigidly attached to the central support andre volves with it while the spider b and bevel wheel I) revolve aroundit.

The inner bobbin carriers f are each mounted on a disk 9 having acircumferential lip g taking into a groove h in a block 6 attached bymeans of screws to the inner spider a so that the disks 9 are free torotate in the spider. The inner bobbin carriers or disk 9 are thus heldand mounted by a small portion of their circumference only leaving theother portion free.

Specification of Letters'Patent.

Application filed November 11, 1907.

Patented May it, 1910.

Serial No. 401,731.

A thread passing arm carrying a thread guide is fixed to one end of alever is carried on each of the outer bobbin carrier arms or spiders b.The other end of the lever 7; is provided with a roller is working in acam race or groove Z fixed on supports carried on the bed of the machineand that as the outer spider orbobbin frame 6 is rotated operates thelever 7a to oscillate the thread arm inward and outward.

The disk carriers 9 are provided with slots g extending from theircircumference inward and as the thread arms j of the outer bobbins arerevolved inward and outward by the cam action the thread guide tubespass into the slots in the disks 9 and behind the inner bobbin sopassing the threads.

As it is not desirable for the guide tubes 7' to rotate the diskcarriers 9 in their passage behind the inner bobbins means are providedfor positively rotating the disks 9 and in the example shown comprises agear wheel at or rack carried by the outer bobbin spider b and engaginga series of rollers '17, or teeth depending from the lower face of thedisk carrier. The slots in the disks are so shaped as not to engage theguide tube.

A guide rail 0 is carried on the spider b and takes the weight of eachdisk carrier which is provided with a suitable shaped block or shoe 7)running on the guide rail 0. To this block or shoe 9 the bobbin carriersf are screwed passing through the disk 9 so that while the disk isperfectly free to revolve the bobbin carrier remains stationary. Slots 7or passages are cut through the guide rail where required for thepassage of the thread carrying arm when passing the threads.

The cam operating the thread passing arm is made in two parts so that itcan be readily taken out and changed so that for example an eightspindle machine can be readily arranged to give either under and overalternately, two under and two over, or one under and three over.

By the method of mounting the inner bobbins, their size can beconsiderably increased over the sizes usually employed.

What I claim and desire to secure by Letters Patent is 1. A braidingmachine comprising inner and outer sets of bobbins rotatable in oppositedirections, disks having the inner bobbins mounted thereon, andsupporting means engaging a portion of the peripheries of said disks,whereby said disks are adapted to be rotated.

2. A braiding machine comprising inner and outer sets of bobbins rotatedin opposite directions, means for passing the thread comprisingrotatable inner bobbin disks provided with slots, a supporting platehaving curved grooves engaging a portion of the periphery of each disk,a two part cam on the bed of the machine, and thread carrying arms orlevers acting on the outer threads and engaging said cam to move thethread carrying arms inward through the slot in the carrier disk andoutward to pass the threads as the disks rotate.

3. A braiding machine comprising two spiders or tables rotated inopposite directions and supporting inner and outer sets of bobbincarriers, toothed disks rotatably mounted by a portion of theirperipheries and supporting the inner bobbin carriers and a toothed rimon the outer bobbin spider gearing with the teeth on the inner bobbindisks to rotate the said disks, thread arms guiding the threads of theouter bobbins and means for operating the said arms to pass the threads.

In testimony whereof I have affixed my signature, in presence of twowitnesses.

EUGENE RANKIN.
